The RMT and the Prison Officers’ Association, which are not affiliated to Labour, both supported Corbyn last year. The RMT has backed Corbyn again this year but the POA is yet to declare. The FBU affiliated to Labour in November last year, meaning it did not have a formal link with the party when it made its nomination last summer.
